/diy/ - Do It Yourself

I've made myself a rack for some of my lighter weights but I dun fugged up and didn't think of a good way to fasten the top part to the wall. Initially I was going to just bolt the entire rack perpendicular to the wall but for some reason I decided to have it at an angle instead. I've already painted everything like a moron so I don't feel like welding something. I'm digging through my hardware and brackets for something that I could bend into shape.

How should I attach it to the wall at the top in a semi-okay manner? Any ideas? Sorry for the crappy drawing.
